DRUGGISTS SIEVE.

$PECIPICATION forming part of Letters Patent No. 351,207, dated October 19, 1886.

Application filed February 15, 1886. Serial No. 192,027. (No model.) Patented in Canada JulylG, 1885, No. 22,094.

To all whom, it may concern:

Be it known that I, ELIZA ELLIs Sco'rr, of the city of Hamilton, in the county of \Ventworth, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Drnggists Sieves; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

My invent-ion comprises a dust'tight box provided with a lid and a sliding bottom, a sieve case or cradle made to rotate in the said box on spindles attached to the circular ends of the said case above and below the line of their centers, and driven by a crank-handle attached to one of them, a cylindrical sieve formed in two halves and hinged together, having closed ends of wood or metal connected with wire-gauze, a catch to hold the two parts of it together, and handles for lifting it. The sieve is secured in the cradle by catches, and the turning of the crank causes the said cradle and sieve to revolve with a continuous Wabbling movement, which throws the substance in the sieve violently from end to cndof it as it revolves.

By reference to thedrawings, forming part of this specification,it will be seen that Figure l is a front elevation of the device closed up ready for operation. Fig. 2 is a similar View partly broken away and in section. Fig. 3 is an end view. Fig. l is a top view of the sifter laid open. Fig. 5 is a perspective view of the cradle detached. Fig. 6 is a perspective View of the sieve detached. Fig. 7 is a vertical sec tion of one end of sieve, showing the tongue and groove on the upper and lower halves used when wood is employed.

A is the lower part of the outer box, and B the upper or lid portion hinged to the former.

O O are the cradle ends connected together by strips of metal a.

D D are the spindles attached to the cradle ends 0 0, above and below the center of each, in a diagonal line, as shown at Figs. 1, 2, and 5, and made to rotate in journals on the part A of the box. By this means a continuous wabbling movement is given to the cradle, and also to the sieve Gwhen it is laid in the cradle and secured therein. The said sieve is cylindrical in shape, formed in two halves hinged together, and composed of wood or metal ends I) b and wire-gauze connected thereto, the ends being at their central edges tongued and grooved.

c is the catch gether.

d d are small handles attached to the sieve for convenience in placingit in and removing it from the cradle.

e e are buttons attached to the cradle ends 0 G to turn over the sieve to prevent it from dropping out of the cradle when revolving.

H is the sliding bottom, shown in Fig. 3 as partially drawn out and uncovering the opening f to allow the sifted material to be easily withdrawn.

The operation of the device may be described as follows: The lid B of the box is thrown back, as in Fig. 3. The lid of the sieve is then opened and the substance to be sifted placed therein. The lid is then closed and secured by the catch 0. The buttons 6 e are then turned inward to hold the sieve. The top of the box is then closed down and the crank-handle E turned to rotate the sieve as long as may be desired,to clean the substance in the sieve, which being accomplished, the bottom H is then drawn out and the contents allowed to drop out at the opening f. The top B is then thrown back, the sieve removed from the cradle, and the sii'tings thrown out, the sieve washed, cleaned, and replaced ready for use again.

It may be observed that the device can be used for domestic purposes as well as for sifting poisonous powder compounds, and the great advantage my device possesses is that during the whole operation of sifting noxious compounds not a particle of dust escapes from it to annoy and poison the operator.

Having thus described my device, what I claim as my invention, and desire to secure by Letters Patent, is

1. In a sieve for drnggists, the box AB and the cradle 0, consisting of. the end disks, the strips (1, the buttons 6 e, the spindles D, and crank-handle E, in combination with the cylindrical sieve G, substantially as and forjthe purpose specified.

2. In a sieve i'or druggists, the cylindrical revolving sifter G, formed in two parts hinged together and provided with tongued and grooved ends I) b, the catch 0, and the handles for securing the two parts tod d, in combination with the eecentrieally-re- Dated at Hamilton, Ontario, this 2d day of volving cradle 0, provided with the spindles October, A. D. 1885. D D and crank E, and the box A B, all constructed substantially as described.

3. In a sieve for druggists, the combination of the box A B, provided with the sliding bot tom H, with the cradle O and sifter G, substantially as and for the purpose specified.
